An aircraft freestream data system can include a first ultrasonic air data system (UADS) configured to sense local acoustic properties at a first location on an aircraft, a first local air data module operatively connected to the first UADS and configured to determine first local air data of the first location and to output first local air data, and a freestream data module operatively connected to the first local air data module. The freestream data module can be configured to receive the first local air data from the local air data module, determine one or more freestream air data parameters based on at least the first local air data, and output the one or more freestream air data parameters to one or more aircraft consuming systems.

An air data probe includes a housing and a probe head with a body, total pressure and alpha chambers, total pressure and alpha ports, and alpha drain ports. The total pressure chamber extends through a radial center of the body. The alpha chambers are disposed radially outward from the total pressure chamber. The total pressure port is disposed in a distal end of the body is collinear with a centerline axis of the body. The total pressure chamber is in fluid communication with the total pressure port and with the housing. The alpha ports are disposed downstream of the total pressure port and upstream of the housing. The alpha chambers are in fluid communication with the alpha ports. The alpha drain ports are disposed downstream from the alpha port and upstream from the housing. The alpha drain ports fluidly communicate with the alpha chamber.

An air data probe includes a probe body and an air data sensing port disposed in the probe body. The probe body includes a barrel region, a tapered head region extending forward from the barrel region, and a tip at a forward-most end of the tapered head region. The air data sensing port is disposed in the probe body at a port location aft of the tip. The probe body has a turbulence-producing geometry originating at the tip that produces a turbulent boundary layer of airflow that extends from the tip to the port location.

A method of isolating a source of an altitude split in a plurality of altitude sensors includes receiving a static pressure reading from a first altitude sensor and receiving a static pressure reading from a second altitude sensor. The method also includes comparing each of the static pressure readings with an expected static pressure value to determine which of the altitude sensors is the source of a split in altitude readings of the altitude sensors.
